The equipment mainly uses the adsorption of activated carbon to remove the active chlorine, color, odor and organic matter in the water. The effluent SDI is less than 5, the working pressure is less than 0.6MPa and the working temperature is 5-50 degrees. The water collector is divided into curved plate and cloth cap. The anticorrosion of the inner surface is divided into epoxy resin lacquer and liner one or two layers, and the operation mode is divided into manual and semi-automatic and automatic.

Shandong Hengfeng Membrane Technology Co., Ltd. was established in June 2007, is a collection of scientific research, production, sales in one of the private joint-stock high-tech enterprises.
